UNITED STATES PATENT OFFICE.

EDWARD WRIGHT, OF WORCESTER, MASSACHUSETTS, ASSIGNOR TO JOHN GOULDING,OF SAME PLACE.

IMPROVEMENT IN BOBBlN-HOLDERS FOR SPINNING.

Specification forming part of Letters Patent No. 50,81 l, dated October3, 1865.

To all whom it may concern;

Be it known that 1, EDWARD \VRIGHT, ot' the city and county ofWorcester, and State of Massachusetts, have invented certain new anduseful Improvements in Bobbin-Holders; and I do hereby declare that thefollowing is a full, clear, and exact description of the same, referencebeing had to theaccompanying drawings, forming a part of thisspecification, in which-- Figure 1 represents a side View of a spindlewith my improvement applied thereto. Fig. 2 represents a longitudinalsection ofFig. 1 when a bobbin is applied, and Figs. 3 and at repre sentdetached parts of the bobbin-holder.

In the drawings, A represents the spindle, and B the whirl; U, thebobbin-holder, and D the bobbin.

My holder is made by first punching out a piece of sheet-steel in theshape shown in Fig. 4, which is then bent into a circular form, with thebars a a bulged out in the center, as show u in Fig. 1. A metal band, E,is then formed from the metal piece F, and the lower end, I), of thestrip of metal is inserted in the ring or band E and headed over thelower edge of the band, as seen at 0, whereby the spring and band aresecurely fastened together, and can be boxed and shipped moreconveniently for use than when the rings and springs are put upseparately. Again, my holderis expansible, and can be applied to aspindle much more conveniently than it could if the ends (I d wereunited or the band E punched whole from a piece of metal.

The holder thus made can be easily applied to the spindles in use, and,even if the band E is made a little smaller than the size of the spindleat the precise point where it is to be used, the holder can be drivendown to any desired point, the band opening a little for that purpose.It will thus be seen that the same holder may be used for spindles ofdifferent sizesan advantage which could not be attained if the'band Ewere whole.

The upper end, 6, forms an expansible band to support the upper part ofthe holder. When the bobbin is stripped on the spindle the bars a yieldand are forced up against the spindle, while the constant pressure ofthe bars against the bobbin hold the latter securely upon the spindle,and with which it revolves when the latter is put in motion.

Brass or any other suitable metal may be used in place of steel to formthe spring-bars.

Having described my improvement, what I claim as my invention, anddesire to secure by Letters Patent, is-

l. A bobbin-holder constructed and operating as above described.

2. Making the bobbin-holder by punching out the metal to form thespring-bars a, substantially as set forth.

3. The combination, with the bobbin-holder 0, of the expansible band E,subs ntiaIIy as set forth.
